NC State Researcher Awarded Grant to Improve Honeybee Health

David Tarpy, of the Department of Entomology and Plant Pathology, leads new CALS research related to honeybee health.With a grant from the Foundation for Food and Agriculture Research’s Pollinator Health Fund, NC State University scientist David Tarpy is researching the impact of pesticide exposure on honeybee colony disease prevalence and reproductive potential.

Tarpy, a professor of entomology and plant pathology and the NC State Extension apiculturist, recently received a $217,000 grant from FFAR, a nonprofit established through bipartisan congressional support in the 2014 Farm Bill. The FFAR grant is being matched by a graduate fellowship from the North Carolina Agricultural Foundation Inc., supporting a Ph.D. student in the NC State Apiculture Program, Joe Milone.

Milone and Tarpy’s research will generate new knowledge about the multiple interacting stressors that lead to declines in pollinator populations. “By studying the interactions among queens, pesticides and disease, we are determining how the entire exposome – or all of the things that the queen and colony are exposed to – affects overall bee health,” Tarpy said.

Noting that managed and native pollinators are vital to many crop production systems and the ecological resources that support them, FFAR Executive Director Sally Rockey congratulated Tarpy and NC State for undertaking research that will inform science-based approaches to improving pollinator health.

FFAR established its Pollinator Health Fund in response to the agricultural threat posed by declining pollinator health. Insect pollinators contribute an estimated $24 billion to the United States economy annually.

NC State is one of 16 organizations that received a total of $7 million in FFAR funding toward research and technology development designed to contribute to healthy pollinator populations that support crop yields and agricultural ecosystems.

ARS Scientist Leads $1 Million Funded Consortium to Seek Honey Bee Disease Controls

The deadly parasitic Varroa mite on the back of this honey bee is one of many insect pests that sugar esters may be useful in controlling. Sucrose octanoate, a sugar ester, can kill the mite without harming the bee. Photo by Scott Bauer.Agricultural Research Service (ARS) entomologist Steven Cook will be leading a $1 million funded international consortium of scientists to seek new controls for Varroa mites, honey bees' number one problem.

Cook, with the Bee Research Laboratory, a part of ARS's Beltsville (Maryland) Agricultural Research Center, will be the principal investigator of a group that will include scientists from the United States, Canada and Spain. ARS is the in-house research agency of the U.S. Department of Agriculture (USDA).

The researchers will be screening a variety of chemical compounds for their ability to control Varroa mites with minimal damage to honey bees on an individual and colony level. Laboratory and field studies will be conducted at facilities in Alabama, Georgia, Maryland and Ohio, as well as in Alberta, Canada.

In laboratories in Nebraska and Spain, scientists also will be using advanced methods to work out an understanding of the molecular mechanisms by which Varroa mites develop resistance to various chemical controls.

Improving knowledge of such mechanisms would provide a better guide to researchers and narrow the field in the future for selecting chemicals worth screening as new control agents for Varroa mites.

The largest single grant for this project is an award of $475,559 to Cook from the Pollinator Health Fund established by the Foundation for Food and Agriculture Research (FFAR) in response to the agricultural threat posed by declining pollinator health. Other funding is coming from participating universities, Project Apis m. and in-kind support from a number of regional beekeepers.

The Honey Bee Health Coalition, a diverse network of key groups dedicated to improving the health of honey bees and other pollinators, also will provide their expertise to facilitate the researchers' efforts.
